Recent Advances in Orthopedic Surgery: Spine, Hand, Foot & Ankle

Spine surgery advances

Recent advances in spine surgery center on minimally invasive and motion-preserving techniques, robotic assistance, computer navigation, and endoscopic approaches. These advances are aimed at improving precision while reducing tissue trauma and recovery times.

Endoscopic spine surgery

Endoscopic spine surgery has emerged as a useful innovation for lumbar discectomy, especially for far lateral disc herniations. The source document notes smaller incisions, less soft tissue disruption, reduced blood loss, and faster recovery compared to traditional open surgery.

The main challenges noted in the source are a steep learning curve related to depth perception and instrument maneuvering in narrow spaces.

Robotic-assisted and computer-navigated surgery

Robotic-assisted and computer-navigated surgery has demonstrated high accuracy in pedicle screw placement while reducing intraoperative time, blood loss, and radiation exposure to operating room staff.

The source notes that long-term clinical outcomes remain comparable to conventional techniques, while enhanced precision and perioperative benefits are driving adoption.

Minimally invasive lumbar fusion

Minimally invasive lumbar fusion approaches, including lateral and oblique approaches such as XLIF and OLIF, along with minimally invasive transforaminal interbody fusion, continue to evolve.

These approaches provide multiple options to optimize spinal alignment and achieve indirect nerve root decompression. Expandable cages can restore collapsed disc space height, and pedicle screws can be placed percutaneously with X-ray or CT guidance to minimize soft tissue disruption.

Motion-preserving spine surgery

Motion-preserving spine surgery, such as laminoplasty and cervical disc arthroplasty, can achieve satisfactory decompression of the cervical spinal cord without the diminished motion and nonunion risks associated with fusion.

Whether disc arthroplasty can reduce the rate of adjacent segment degeneration remains controversial.

Spondylolisthesis and reduced morbidity

The source also notes minimally invasive options for treating conditions such as spondylolisthesis with reduced morbidity.

Enhanced Recovery After Surgery protocols

Enhanced Recovery After Surgery protocols are being integrated with minimally invasive techniques to further reduce hospital stays and postoperative pain.

Hand surgery advances

Recent advances in hand and wrist surgery include research related to compressive neuropathy, distal radius fractures, opioid-free multimodal analgesia, and artificial intelligence in wrist imaging.

Compressive neuropathy and amyloidosis screening

The prevalence of positive amyloidosis diagnoses among patients undergoing tenosynovial biopsy to screen for amyloidosis during carpal tunnel release was investigated in a retrospective study.

When patients with spinal stenosis and cardiac disease who satisfied the screening questions were included, the cohort of 62 patients demonstrated a positive biopsy rate of 22.5%.

Distal radius fractures

A JBJS study investigated radiographic and clinical outcomes following treatment of distal radial fractures in 366 patients. A dorsal tilt greater than 5 degrees was strongly correlated with worsening clinical outcomes, except in patients older than 75, where a difference was not observed until dorsal tilt was greater than 20 degrees.

Opioid-free multimodal analgesia

Opioid-free multimodal pain regimens were found to provide adequate pain relief following various hand surgeries, according to a systematic review that included 1,480 patients.

The review also showed that these regimens required increased use of rescue analgesia. The source notes that limiting opioids prescribed in hand surgery is promising, but protocols still need optimization.

Artificial intelligence in wrist imaging

A recent study investigated a deep learning algorithm for detecting perilunate and lunate dislocations on lateral wrist radiographs. The algorithm had a sensitivity of 93.8%, a specificity of 93.3%, and an accuracy of 93.4%.

The researchers concluded that the algorithm has potential to improve clinical sensitivity and help prevent delayed or missed diagnosis of these injuries.

Foot and ankle advances

Recent advances in foot and ankle care include updated terminology, weightbearing CT imaging, minimally invasive techniques, early weightbearing after ankle fracture repair, and biologics for selected cartilage restoration procedures.

Progressive collapsing foot deformity

Adult acquired flatfoot deformity and posterior tibial tendon dysfunction is now called progressive collapsing foot deformity.

Weightbearing CT scan is described in the source as the gold standard imaging modality to evaluate pathology.

Minimally invasive foot and ankle techniques

Minimally invasive foot and ankle surgical techniques have emerged. The source notes that forefoot deformities can be treated through small poke-hole incisions with equivalent outcomes and correction.

The source also notes that minimally invasive Achilles tendon surgery results in much lower surgical time, soft tissue disruption, and incidence of infection.

Minimally invasive ankle fracture fixation with an intramedullary nail results in less operative time and fewer wound healing complications.

Early weightbearing and rehabilitation

A recent randomized controlled trial showed that early weightbearing and rehabilitation following ankle fracture surgical repair results in quicker recovery with equivalent long-term results.

Biologics for osteochondral lesions of the talus

The addition of biologics, such as bone marrow aspirate concentrate, to cartilage restoration procedures for osteochondral lesions of the talus significantly reduced revision surgery rates.
