Summary
Proximal row carpectomy with lateral meniscal allograft interposition (LMAI) offers a motion-preserving alternative for wrist arthritis when standard procedures are contraindicated. Early results suggest comparable function to proximal row carpectomy alone.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Musculoskeletal Research
Background:
- Proximal row carpectomy (PRC) is not suitable for wrists with pre-existing arthritis in the proximal capitate or radiolunate fossa.
- Patients with these contraindications often undergo wrist arthrodesis, leading to functional limitations.
Purpose of the Study:
- To evaluate the efficacy of lateral meniscal allograft interposition (LMAI) combined with PRC in patients with symptomatic wrist arthritis.
- To compare wrist function after PRC with LMAI to that of PRC alone.
- To assess the short-term durability of the lateral meniscal allograft.
Main Methods:
- A retrospective review of nine wrists that underwent PRC with LMAI between 2006 and 2012.
- Assessment of patient demographics, complications, and graft failure rates.
- Clinical examinations, Disabilities of the Arm, Shoulder, and Hand (DASH) scores, and radiographic analysis were performed.
Main Results:
- Four patients met inclusion criteria with an average follow-up of 4.2 years.
- Average DASH scores were 24 (range 9-33).
- Radiographic analysis showed a decrease in radiocapitate joint space from 2.8 mm to 1.8 mm, with no progression to arthrodesis.
Conclusions:
- Early outcomes of PRC with LMAI appear comparable to PRC alone.
- This combined procedure may serve as a viable short-term, motion-preserving option for patients ineligible for PRC.
- Lateral meniscal allograft interposition shows promise in managing specific wrist arthritis cases.
